High-quality PCB design – This second-generation board is designed with care, and a great reference for your own designs. Four-layer PCB with dedicated ground and power planes, six external ground connections, power distribution and decoupling capacitors implemented by the book for all ICs.

Open source bootloader - The TinyFPGA BX implements its own open source USB bootloader. Upon power-up, USB bootloader is loaded from SPI flash and becomes active. It appears on the host computer as a virtual serial port device.

Small form-factor is breadboard friendly - There’s plenty of space on either side for connecting jumpers or components. There is no smaller FPGA board available with this many logic resources.

  • Programming interface: USB 2.0 full-speed (12 mbit/sec)
    • Programming supported by open-source tool chain
  • 8 MBit of SPI Flash
  • Onboard 3.3 V (300 mA) and 1.2 V (150 mA) LDO regulators
